The Norwegian emission inventory

The Norwegian emission inventory is a joint undertaking between the Norwegian Pollution Control Authority (SFT) and Statistics Norway. The Norwegian Pollution Control Authority is responsible for the emission factors and for providing data from specific industries and sources, while emission figures are derived from models operating at Statistics Norway. Statistics Norway is responsible for developing the emission models, for the collection and development of activity data, and for the calculations. Emission data are used for a range of national applications and for international reporting.

This report document the methodologies used in the Norwegian emission inventory of greenhouse gases (GHG), acidifying pollutants, heavy metals (HM) and persistent organic pollutants (POPs). The documentation will also serve as a part of the National Inventory Report submitted by Norway to the United Nation Framework Convention on Climate Change (UNFCCC), and as documentation over the reported emissions to UNECE for the pollutants restricted by CLRTAP (Convention on Long-Range Transboundary Air Pollution).

This report replaces the previous documentations of the emission model, Rypdal (1993), Rypdal (1995b) and Flugsrud et al. (2000). The most important changes are that heavy metals and POPs have been included, text has been updated where appropriate, the structure has been changed to correspond to the nomenclature used for international reporting and information about QA/QC (Quality Assurance/ Quality Control) and uncertainties have been added.

The Norwegian Emission Inventory; Documentation of methodologies for estimating emissions of greenhouse gases and long-range transboundary air pollutants is also avable at http://www.ssb.no.
